` Application filed May 29| 19.05. Serial'No. 262,751.

To all whom 'it may concern;

, Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Heels, of which the following is a s eciflcation.

This invention relates to eels for boots or shoes. Y l

In the manufacture of boots and shoes, as is well known, heels are commonly attached by machines which act iirst to press the heel u on the heel seat of the shoe with considera le pressure and then to drive the attaching nails into the heel.

An` object of my invention is to provide a heel which is so formed that an accurate location of said heel upon the boot or shoe-preliminarily to driving the nails will be facilitated. In vthe operation --of heel attaching machines there is liability of a heel slipping as itis pressed upon the heel seat. .A compressed heel is more or less Wedge-shaped according `to different circumstances and its heel seat face is transversely concavel as is well lknown to accommodate the transverse conveXity of the heel seat. In pressing a heel upon its seat, therefore, it will be seen that the surface of contact between the heel and the heel seat may be more or less oblique to the line of pressure, and that consequently there will be some tendency for the pressure to force the heel out of 'position with relation to its seat. 'The heel seat face of a compressed heel generally does not accurately fit the heel seat, so that as the heel is pressed upon its seat it may engage at first only a small ortion of the heel seat-area. This lack of) conformity between heel and heel seat may cause an increased tendency to displacement ofthe heel in the heel attaching operation. Moreover, the heel seat of a boot or shoe, yas is well known, is the grain side of the leather, and immediately prior to the heel attaching operation is commonly quite smooth so that slipping of the heel is facilitated on this account. If the heel seat face of the compressed heel should also be the grain side of the leather and have the high degree of smoothness imparted thereto by 'the heel 'compressing machine, liability of slipping would be still further increased.

Furthermore, the application of cementto the heel seatA face of a heel decreases fria;

g in the attaching i -55 some tional lresistance to slipp operation, as will be obvious. I e v In attaching heels to boots and shoes difficulty has been heretofore experiencedzin securing an accurate location of a heel upon its vheel seat on account'of the tendency-to l displacement above referred to, the liability of slipping being more or less according. to circumstances. It is desirable thattheheel be positioned accurately upon. vits seat in the o eration of driving the nails, for while a s ight inaccuracy in position may be at times substantially cured in trimming the heel,

this cannot always be done, and' if the 'inaccuracy be considerable it may be impossible to trim the heel to secure the symmetry of form desired.

It-has heretofore been generally regarded as impracticable, mainly for reasons Such as above given, to make the heel seat face of the heel the grain side of the leather, a1- though there are considerations which render it desirable. For. example, where compressed heels are sold as a separate article of manufacture it is of course desired tomake their appearance as attractive as' possible and the appearance of the heels is much improved if their 'exterior faces and particularly "their heel seat faces are somewhat liinished. The natural` .smoothness of the grain side of the leatheris such that Where this side is outside the dies of the heel compressor make it extremely smooth, giving the leather a more attractive a pear'ance than where the esh side is outsi e. Moreover, where the heel seat face of the heel is the grain side of the leather, a close union with the outersole is permitted at the edges,`

since the two grain surfaces are irm- 'and even and mayl be readily brought into close contact.-

According to m invention avheel is provided upon its hee seat face with projections formed and arran ed -to preventdisplacement ofthe heel w en itis y ressed upon its seat. Said projections re erably are provided in molding the hee and are so formed that in pressing 'the heel upon the heel seat they may indent or enetrate to a limited extent thefaceof theieelf art of the youtersole. In theheel shown eylarearranged top-lift face.

In the drawings which illustrate a heelv showing-one embodiment of the `invention,- Figure 1 is a persprective view of said heel; Fig. 2 isa view inJ ont elevation of the heel;

Fig. 3 is a view in longitudinal vertical sec- `tion of the heel and Fig. 4 is a view in perspectiveof the heel, showing the outer or the dr wings, a represents a heel constituting th referredV embodiment of the invention, sai heel being formed of a series of supelposed j he external lifts b, and c are preferably of'leather, while the remaining lifts may be madeTillf desired, of less expensive sube ranged withtheir grain sides outward. A be arranged between the inner or heel seat lift c and the next adjacent lift, said rand beingA rovided to facilitate the production of the esired concavity in the heel seat face of the heel. It will be seen that with the rand arranged in this manner the heel seat face of the heel isformedby a single piece of leather.

The heel is molded in a compressing ma-4 chine to impart to it the desired form and density. In the molding or compressing opheel seat face of the heel is provided with numerous rojectionsf, said projections beingprefera ly arranged as shown eel 1s provided with the usual bevel at the breast which, as is well known, prevents the when the heel is pressed upon theheel seat art lof the sole. -Said bevely is preferably eft smoth for the reason .that it is unnecesv sary to provide projections upon this part of the heel seat face andthe general appearance roved if it jis 4left smooth and ilty'of the sole being-marred iby pressureof such roughened face upon it in attaching the heelis .thusprevented The raised `parts s or 'projections molded u onthegreater part 'of theiheel seat face of t e heelmay be of any desired form andaar` rangement-.q` It is desirable, however, that theyr be sharply ,may indent or penetrate -t'o'a limited extent leather,

lifts of leather or other ma-` jforA retaining cement lifts b and c are preferably ar-v defined in order thatwhen' the heel is pressed uponjtheheel seat they ingan inner lift' withthe grain side outward;

i the face of the ontersole.. In-the heel shown the projectionsare formed as approximatelyconical-or' yramidal. It will be seen k,that on account 'o thesehprojections being molded upon the grai' s' e of the leather they possess considerab e resistance to crushing pressure. The hardness` of the projections and' .their 'pointed shape aid in preventing sliping of a' heel wit relation to a leather surace against which it may be pressed.` It

will be seen that the vprojections f also serve to retain cement in case it is applied to the heel seat face of a heel preliminarily to pressing it upon its seat. If said face is' smooth the cement will be squeezed out at the sides in pressing the heel upon its seat. Where this face is of the flesh side of the leather the cement is absorbed to some extent by the but on account of the grain side of leather being considerably m'ore ldense and iirm 4than 'the flesh side it has little absorptive power. Hence, if there is noprovisipn where the heel seat race ofthe heel is the` grain side of the leather l there is considerable liability of said cement lnot having its intended function of holding the heel in close union with 'the heel seat.

The projections upon the heel seat face ofv the heel are referably omitted at the ex-v treme edge o said face, as shown -in This feature is ofadvantage in mits a ortionof the stock to be removed in the hee trirninilvig o eration without causing said projections to) j the lsides or curved end of the heel.

At .the -same time. that molded upon the heel seat ace of the'heel shown the outer or top lift face of'thevheel is provided with depressions pshown'in 4- arran ed nearfthe-,center-o the-heel. ter
